Description

Technical Field

[0001] This utility model relates to the field of precision material transport equipment, and in particular to a sheet turnover box. Background Technology

[0002] In the production and logistics of precision sheet materials, turnover boxes serve as the core carrier, and their performance directly affects product yield and cost. Currently, ordinary turnover boxes on the market often face the following problems when used for transporting precision sheet materials: First, the sealing performance is insufficient. Most of them use a single sealing strip or a simple cover pressing structure, which is difficult to effectively isolate moisture and dust in complex transportation environments and cannot meet the increasingly high cleanliness requirements of high-end manufacturing. Secondly, the structural design needs to be optimized. While ensuring sufficient rigidity and strength to achieve reliable protection, the box is often heavy, which is not conducive to manual handling and energy consumption control. Moreover, there is a lack of effective horizontal limiting mechanism when stacking, which poses a risk of slippage or even overturning. Secondly, the locking mechanism lacks protection, and the exposed buckles are easily opened accidentally due to collisions and vibrations during handling and transportation, causing the lid to loosen and resulting in contamination or damage to the internal materials. Finally, the limited functionality and poor adaptability of the internal structure make it difficult to quickly replace the inner lining with a matching one for different production lines and sheet sizes, reducing the versatility and efficiency of the turnover box and increasing the equipment costs for enterprises.

[0003] Existing sheet material transport containers are inadequate in terms of sealing, liner fixation, stacking stability, and buckle security, which can easily lead to materials getting damp, shifting, or being damaged, affecting transportation efficiency and product quality.

[0004] Therefore, there is an urgent need in this field for a turnover box that combines high sealing performance, high structural strength, safe stacking protection, and rapid liner adaptation capability to meet the severe challenges of safe, efficient, and low-cost turnover of high-precision sheets. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a sheet turnover box, which solves the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a sheet turnover box, including a box lid, a box body, a sealing structure and multiple fastening structures, wherein the box lid and the box body are sealed by the sealing structure and fixed by the fastening structures; The lid is rectangular, with a textured surface on the top surface and limiting protrusions at the four corners of the top edge. The lid has multiple handles on its sides, and grooves are provided on the sides adjacent to the handles. Multiple double-hole mounting slots are evenly opened on the four sides of the lid, and an integrally formed soft sealing line is provided on the bottom edge. The inner surface of the box is provided with crisscrossing reinforcing ribs, and each of its four sides is provided with a single-hole mounting slot corresponding to the position and number of the double-hole mounting slot. The double-hole mounting slot and the single-hole mounting slot together support the mounting buckle structure. The sealing structure is a two-stage seal. The first-stage seal is formed by pressing the sealing line against the sealing edge of the box above the box. The second-stage seal is formed by the sealing groove on the upper edge of the box and an irregularly shaped soft sealing ring that is interference-fitted into the sealing groove.

[0007] As a further technical solution of this utility model, two handles are symmetrically arranged on the front and rear sides of the box cover, and one handle is arranged in the middle of the left and right sides.

[0008] As a further technical solution of this utility model, the upper end of the sealing ring is semi-circular, the lower end of the sealing ring is rectangular, and the rectangular part is interference-fitted with the sealing groove; When the lid is closed, the lid seals along the semi-circular end of the sealing ring, and the sealing line is made of soft plastic or rubber.

[0009] As a further technical solution of this utility model, the inner side of the box is provided with an inner lining plate, and the lower end of the inner lining plate is provided with a curved structure and a flat structure.

[0010] As a further technical solution of this utility model, the four outer perimeters of the inner side of the box and the four outer perimeters of the inner lining plate form a universal quick-clamp structure, and the contact surface of the universal quick-clamp structure is a rough surface with a narrow upper part, a wide lower part, and a small angle of inclination.

[0011] As a further technical solution of this utility model, the buckle structure includes a buckle body and a protective cover, wherein the buckle body is connected to the double-hole mounting groove and the single-hole mounting groove by fasteners; The protective cover is rectangular and is connected to the side of the box cover via a pivot.

[0012] As a further technical solution of this utility model, the buckle body is a lever-type buckle, which is fixed to the double-hole mounting groove at the top and connected to the single-hole mounting groove at the bottom through a locking hook.

[0013] As a further technical solution of this utility model, a locking space is formed between the four limiting protrusions at the top of the box cover. The lower surface of the box body is provided with limiting protrusions that complement the locking space. The bottom end of the box body can be locked in the locking space at the top of the box cover by the limiting protrusions, so as to interlock the two turnover boxes when they are stacked.

[0014] This utility model provides a sheet turnover box, which has the following advantages compared with the prior art: 1. This design features a sheet material turnover box with a two-stage sealing structure between the lid and body, ensuring excellent waterproof and dustproof performance. The first seal, consisting of a sealing line, and the second main seal, consisting of a shaped sealing ring, form double protection, greatly enhancing waterproof and dustproof capabilities. Furthermore, the design of reinforcing ribs and textured surfaces ensures structural strength while achieving lightweighting. The lid and body, through textured surfaces, reinforcing ribs, and side grooves, optimize materials and reduce weight while maintaining overall rigidity and strength.

[0015] 2. This design of a sheet turnover box utilizes the complementary interlocking of the limiting protrusions at the four corners of the top of the box lid and the limiting bosses on the box body to achieve horizontal limiting and prevent stacking slippage. After the protective cover is closed, the sides are flat, further improving the stacking regularity. In addition, the buckle structure with the protective cover effectively improves the safety and stability during transportation and stacking. The rectangular protective cover on the outside of the buckle can effectively prevent the buckle from being accidentally opened during transportation. At the same time, the limiting protrusions of the box lid and the limiting bosses of the box body cooperate with each other to ensure the horizontal limiting and stability when multiple turnover boxes are stacked vertically.

[0016] 3. The sheet turnover box designed in this paper features a universal quick-release structure that enables quick, tool-free replacement of the inner lining, providing strong adaptability. The universal quick-release structure on the inside of the box also enables quick, tool-free disassembly and assembly of the inner lining, allowing a single turnover box to flexibly adapt to various production lines and sheet specifications, thereby improving versatility and turnover efficiency.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a sheet turnover box technical solution: a sheet turnover box includes a box cover 1, a box body 2, a sealing structure 3 and multiple fastening structures 4. The box cover 1 and the box body 2 are sealed by the sealing structure 3 and fixed by the fastening structures 4. like Figure 4 As shown, the lid 1 is rectangular, with raised and recessed textures 14 on the upper surface to enhance overall rigidity and prevent deformation. Limiting protrusions 13 are provided at the four corners of the top edge, which cooperate with the limiting protrusions 21 of the lower box 2 to achieve horizontal limiting when multiple turnover boxes are stacked vertically. Two handles 11 are symmetrically arranged on each of the front and rear sides of the lid 1, and one handle 11 is arranged in the middle of each of the left and right sides for easy manual or mechanical handling. To strengthen the structural strength of the handles 11 and achieve weight reduction, side ribs 12 are provided near all handles 11. Multiple double-hole mounting slots 15 are evenly opened on the four sides of the box cover 1. It should be noted that an even number of double-hole mounting slots 15 are arranged on the front and rear sides of the box cover 1, and an odd number of double-hole mounting slots 15 are arranged on the left and right sides. These double-hole mounting slots 15 are used for quick installation and fixing of the buckle structure 4. An integrally formed soft sealing line 33 is provided at the bottom edge of the box cover 1. The sealing line 33 is made of soft plastic or rubber. The sealing line 33 of the box cover 1 is pressed with the box body sealing edge 32 of the box body 2. After elastic deformation, a preliminary barrier is formed, that is, a first-level seal is formed. Four limiting protrusions 13 form a locking space at the top of the box cover 1. The lower surface of the box body 2 has limiting protrusions 21 around its perimeter that complement the locking space. The bottom of the box body 2 can be locked into the locking space at the top of the box cover 1 through the limiting protrusions 21. This allows two turnover boxes to be interlocked when stacked, preventing the upper box from sliding.

[0021] like Figure 7 As shown, the inner surface of the box 2 is provided with crisscrossing reinforcing ribs 22, which effectively reduces the weight while ensuring the load-bearing strength and rigidity of the box 2. The four sides of the box 2 are equipped with single-hole mounting slots 23 corresponding to the position and number of double-hole mounting slots 15. Their position and number correspond one-to-one with the double-hole mounting slots 15 on the box cover 1. The double-hole mounting slots 15 and the single-hole mounting slots 23 jointly support the installation buckle structure 4.

[0022] like Figure 8 As shown, the buckle structure 4 includes a buckle body 41 and a protective cover 42. The buckle body 41 is preferably a lever-type buckle. Its upper part is connected and fixed to the double-hole mounting groove 15 of the box cover 1 by fasteners (such as bolts), and its lower part is connected and fixed to the single-hole mounting groove 23 of the box body 2 by its locking hook. By turning the lever, the turnover box can be easily opened and closed.

[0023] The protective cover 42 is rectangular and connected to the side of the box cover 1 via a pivot. It can rotate around the pivot. During transportation and stacking, the protective cover 42 is closed. Its regular rectangular shell can completely cover the internal buckles, effectively preventing the buckles from being accidentally opened due to external collisions, vibrations or snagging, which greatly improves transportation safety. At the same time, after all the protective covers 42 are closed, the side of the turnover box becomes a flat rectangular surface, ensuring the regularity and stability when multiple turnover boxes are stacked horizontally.

[0024] like Figure 4-6 As shown, the sealing structure 3 is a two-stage seal. The first-stage seal is formed by the sealing line 33 pressing against the sealing edge 32 of the box body 2. When the box cover 1 is closed, the soft sealing line 33 undergoes elastic deformation and fits tightly against the sealing edge 32 of the box body, forming a preliminary sealing barrier. The second-stage seal is formed by the sealing groove 34 on the upper edge of the box body 2 and the irregular soft sealing ring 35 that is interference-fitted into the sealing groove 34. The upper end of the sealing ring 35 is semi-circular, and the lower end of the sealing ring 35 is rectangular. The rectangular part is interference-fitted with the sealing groove 34. When the box cover 1 and the box body 2 are closed, the sealing edge 31 of the box cover presses down on the semi-circular end of the sealing ring 35, causing it to deform significantly, thereby forming a highly reliable sealing interface and thus forming a second-stage seal. This irregular structure ensures excellent sealing performance even in harsh environments.

[0025] like Figure 5 and 6As shown, the inner side of the housing 2 is provided with an inner lining plate 251. It should be noted that the inner lining plate 251 is a conventional inner lining plate in this field, and multiple longitudinal adjustment grooves and transverse adjustment grooves are symmetrically formed on the inner lining plate 251 (i.e., Figure 6 (a) In the inner lining plate 251, each longitudinal adjustment groove and each transverse adjustment groove is provided with an adjustable fixing structure (i.e., Figure 6 b) is used to position sheets of different sizes. The longitudinal adjustment groove and the transverse adjustment groove are symmetrically provided with sliding grooves on both sides to facilitate the sliding limit of the sliders on both sides of the adjustable fixing structure. The adjustable fixing structure can be slidably adjusted in the longitudinal adjustment groove and the transverse adjustment groove, and is positioned and fixed by tightening the fastening screw against the bottom of the groove. This structure is a conventional sheet fixing structure in the field.

[0026] The four inner perimeters of the housing 2 and the four outer perimeters of the inner lining 251 form a universal fast-delivery structure 24, the specific form of which is as follows: Figure 9 As shown, the contact surface of the universal quick-clamp structure 24 is a rough surface with a narrow upper surface, a wide lower surface, and a small-angle inclination 241, forming a mortise and tenon structure. The rough surface and mortise and tenon connection increase the friction and locking force. The friction and locking force are adjusted by changing the angle of the small-angle inclination 241 and the roughness of the contact surface. Furthermore, the lower end of the inner lining plate 251 is equipped with a curved structure 242 to facilitate the smooth entry of the inner lining plate 251 into the housing 2. In addition, the lower end of the inner lining plate 251 is equipped with a flat structure 243, which is beneficial to the stability of the contact between the inner lining plate 251 and the bottom of the housing 2 after installation. Based on the above universal quick-clamp structure 24, the inner lining plate 251 can be quickly and stably clamped and replaced without the use of any tools.

[0027] The working principle of this utility model is as follows: Before use, select a suitable inner lining plate 251 according to the sheet specifications, and push the inner lining plate 251 vertically downward into the box 2 along the tilt direction of the universal quick-clamp structure 24 until the flat structure 243 fits against the bottom of the box 2. The friction of the rough surface and the tenon and mortise structure make the inner lining plate 251 firmly fixed. Next, the precision sheet is positioned and fixed by the adjustable fixing structure on the inner lining plate 251 to ensure that the sheet does not shift. Then, the box cover 1 is placed on top of the box body 2. At this time, the sealing line 33 is pressed together with the sealing edge 32 of the box body to form a primary seal. The sealing edge 31 of the box cover presses down on the semi-circular end of the sealing ring 35 to deform it and form a secondary seal. Furthermore, by levering all the latch bodies 41, the locking hooks engage with the single-hole mounting slots 23, thus locking the lid 1 and the body 2. Then, the protective cover 42 is rotated to cover the latch bodies 41 to prevent accidental opening. Finally, the multiple turnover boxes are stacked vertically. The limiting protrusion 13 of the box cover 1 is embedded into the limiting protrusion 21 of the box body 2 below to achieve horizontal limiting. The protective cover 42 makes the sides flat and ensures the stability of the stack.

[0028] In addition, it should be noted that the main body material of the lid 1 and the body 2 is preferably ABS engineering plastic, which has high strength and light weight. The sealing line 33 and the sealing ring 35 are preferably EPDM rubber or aging-resistant silicone rubber. The buckle body 41 is preferably made of metal, the protective cover 42 is preferably made of PVC, the inner lining 251 is preferably made of PP, and other specific materials can be selected according to actual application requirements.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
